摘　　要：既有路面检测需要评估已建成的路面在长期使用和环境因素作用下的稳定性。但传统的稳定性检测方法往往存在较大的限制,例如贝克曼梁法等方法仅能反映路面的静力性能,难以反映路面的动力性能。为了克服静力检测的缺陷,文章提出了基于加速度响应的既有路面稳定性检测技术,通过计算路面振动过程中的反应谱和频响函数差异,从而反映其时程特性和频域特性,再结合相关系数法,进行既有路面的稳定性评价指标计算,从而能够全面反映路面的动力特性,提高检测的准确性和可靠性。Existing road surface inspection requires evaluating the stability of the constructed road surface under long-term use and environmental factors.However,traditional stability testing methods often have significant limitations,such as the Beckman beam method,which can only reflect the static performance of the road surface and is difficult to reflect the dynamic performance of the road surface.In order to overcome the shortcomings of static testing,the article proposes an existing pavement stability detection technology based on acceleration response.By calculating the response spectrum and frequency response function differences during pavement vibration,the time history and frequency domain characteristics are reflected.Combined with the correlation coefficient method,the stability evaluation index of the existing pavement is calculated,which can comprehensively reflect the dynamic characteristics of the pavement and improve the accuracy and reliability of detection.
